About family everyone concerned about the cost of installing solar photovoltaic power generation system problem, in fact, there are only two influence factors: 1, the hardware cost if families need to install solar photovoltaic power generation system, need to prepare money should be not less than 10000 yuan, with
the factors influencing home installation of solar photovoltaic power generation system cost only two. 1. Hardware costs if a family need to install solar photovoltaic power generation system, need to prepare not less than 10000 yuan of investment, to determine the size of this can be according to the roof. Under normal circumstances, photovoltaic power generation system can generate electricity more than 25 years. Although some families of investment cost is slightly higher, but overall, the income is much greater than the investment cost. 2. National subsidy policy of household photovoltaic power generation is a policy support project of our country at present. Of state subsidy policy is a family per KWH 0 can be obtained. 42 yuan subsidy standards. If failed to use their own power, they can use the national grid for online payment and collection. So, in most cases, they can in a few years back to the original cost. In short, the solar photovoltaic power station is a very safe power generation systems. Solar power technology as an inexhaustible, inexhaustible new energy environmental protection will get a great development.
